Abstract

1. Клапан сброса давления для масляных трансформаторов и переключателей ступеней обмоток трансформаторов, содержащий фланец (1) корпуса, имеющий отверстие (2), соединенное с объемом трансформатора или переключателя ступеней обмоток трансформатора, причем фланец (1) корпуса в стационарном состоянии закрыт крышкой (4) клапана, на которую в направлении закрывания действует усилие пружин (13, 14), причем между отверстием (2) фланца (1) корпуса и крышкой (4) клапана предусмотрено окружное уплотнение (5), причем предусмотрена дополнительная неподвижная окружная рабочая кромка (28) уплотнителя, корреспондирующая с отогнутой книзу стаканообразной краевой областью (29) крышки (4) клапана, отличающийся тем, что рабочая кромка (28) уплотнителя имеет по меньшей мере одно отверстие, нарушающее полную герметичность.2. Клапан сброса давления по п.1, отличающийся тем, что по меньшей мере одно отверстие выполнено в виде по меньшей мере одной выемки (31-34), нарушающей герметичность с уплотнительного края рабочей кромки (28) уплотнителя.3. Клапан сброса давления по п.2, отличающийся тем, что посредством по меньшей мере одной выемки (31-34) нарушается герметичность максимум 5% окружного уплотнительного края рабочей кромки (28) уплотнителя.1. Pressure relief valve for oil-filled transformers and transformer winding stage switches, containing a housing flange (1) having an opening (2) connected to the volume of the transformer or transformer winding stage switch, and the housing flange (1) in the stationary state is closed by a cover (4 ) of the valve, on which the force of the springs (13, 14) acts in the closing direction, and between the hole (2) of the flange (1) of the body and the cover (4) of the valve, a circumferential seal (5) is provided, and an additional fixed circumferential working edge (28 ) of the seal, corresponding to the glass-shaped edge area (29) of the valve cover (4) bent downwards, characterized in that the working edge (28) of the seal has at least one hole that violates complete tightness. Pressure relief valve according to claim 1, characterized in that at least one hole is made in the form of at least one notch (31-34) that breaks the tightness from the sealing edge of the working edge (28) of the seal. Pressure relief valve according to claim 2, characterized in that at least one recess (31-34) breaks the tightness of a maximum of 5% of the circumferential sealing edge of the working edge (28) of the seal.
